Testing a Standalone Unit

Testing a Standalone Unit
This section describes how to perform a G24 functionality test, whose purpose is to:
•
Introduce the user to the G24
•
Explain how to work with the G24 unit
•
Describe how to evaluate basic G24 features
The test setup provides a wide platform through which a G24 unit can be evaluated. The specific
test procedure described below covers only a few of the G24's many features. Using this setup,
you can perform several additional tests on the G24.
The test is performed using two modems, one of which is the G24. The modems communicate
with each other through a single computer, which also controls their operation.
The test requires knowledge about the operation of the G24 Developer's Kit, terminal
applications and AT commands. Refer to relevant documentation for assistance.
To perform the test, you need the following:
•
A G24 OEM cellular engine unit
•
A G24 Developer's Kit
•
A desktop or laptop computer, which includes:

Test Setup

To Setup the G24 Test
Follow this procedure
1. Verify that the computer you intend to use for the test is equipped with a working
line modem
You can use a second G24 unit instead of the line modem. When doing so, you must repeat
the setup procedure that follows for the additional G24.
2. Set up the G24 and the Developer Board as described in
"Chapter 2: Developer Board and Interfaces Description"
(Motorola part no. 6889192V26)
3. Verify that the G24 has adequate reception from the local GSM network
4. Connect the Developer Board's RS232 port to the computer's serial port
5. Open a terminal application window (such as HyperTerminal) and configure it to operate
with the serial port occupied by the G24
